Privacy Policy

Last updated October 1, 2026

This policy explains how Comixi handles data when you use the Comixi website and its browser extension. Contact us at comixi@proton.me with privacy questions or requests.

The extension uses the websites you choose for site profiles to find comic pages and chapter links. It saves your site patterns, profile settings, reading preferences, and chapter catalogs (including chapter titles and URLs) in extension storage in your browser. It also stores a short lived record when you move between chapters. These profiles and catalogs are not uploaded to Comixi as a collection.

Viewing or downloading a page can contact the website or image host that provides it. Your browser may send that site's cookies with those requests. Those sites have their own privacy practices.
Translation and colorization

When you ask Comixi to translate or colorize a page, the extension downloads the selected image and sends its bytes to Comixi for processing. The request also includes the image filename and, for translation, your language choices. The filename may come from the image's address. Comixi returns the processed image to your browser. Comixi does not save uploaded images.

Comixi runs image recognition and colorization in its processing service. For translation, text extracted from the image and the selected languages are sent to Google Translate. Google may handle that text under its own terms and privacy practices. Simply reading a page in Comixi Reader does not upload the page image to Comixi for processing.
Accounts, sign-in, and billing

An account is optional for basic Reader use. If you sign in, Comixi stores your account ID, name, email address, profile image when provided, session records, plan status, and related identifiers in its service database. Session records can include your IP address and browser information. If you use Google or Discord sign-in, those providers handle your sign-in and may share basic account details with Comixi.

With your extension setup consent, Comixi checks its own session cookies to keep your website sign-in and plan in sync with the extension. Selected account details are cached in extension storage. Comixi does not read unrelated website cookies for this account sync.

Paid checkout and subscription management use LemonSqueezy. Checkout can pass your Comixi account ID and email address to LemonSqueezy. Comixi receives subscription status, customer and subscription identifiers, and billing email information needed to update your plan. Payment details you enter at checkout are handled by LemonSqueezy.
Usage and service records

For usage limits, Comixi records the processing feature, date and time, IP address, and your account ID if you are signed in. The website uses authentication cookies to keep you signed in. Service logs and error reports can include request paths, IP addresses, response status, processing times, errors, and, for billing events, account or billing identifiers. We use these records to operate, secure, and troubleshoot the service.

Cloudflare hosts the website and account database. Google Cloud hosts image processing and service logging. Sentry may receive processing error reports. Google Translate receives text for requested translations. Google and Discord handle sign-in when you choose them; LemonSqueezy handles paid checkout. The website also loads fonts from Google Fonts, which can receive connection information such as your IP address. Support email is handled through Proton Mail. These providers may process information under their own privacy policies.
Retention and your choices

Uploaded images: processed for your request and not saved by Comixi.
Browser data: site profiles and chapter catalogs stay in your browser until you delete them or remove the extension. Turning Comixi off stops its features but leaves saved profiles in place.
Usage records: a daily cleanup job deletes Comixi's processing-quota records once they are older than 30 days.
Account records: remain while your account is active. Signed-in users can delete unbilled accounts in Account Settings. If a paid subscription can be verified, you can cancel renewal and schedule account deletion after the paid period, or choose immediate deletion. Accounts with billing details that cannot be verified automatically require support review. You can also request access or correction. We will verify account ownership and explain if any records must be retained for billing, security, or legal reasons.
Service logs: retention depends on the hosting and error-reporting service. Google Cloud's default application log bucket is currently configured for 30 days; other required or provider logs may be kept longer.


You can delete a site profile in the extension settings and clear its chapter setup there. You can turn off Comixi's data use from the extension's setup page or remove the extension. You can delete an account from Account Settings; this removes its Comixi sign-in sessions and linked usage records, but does not remove locally saved extension profiles. For a paid account, we cancel future renewal before deletion. Scheduled deletion happens after Lemon Squeezy confirms the paid period has expired; immediate deletion ends Comixi access right away. Comixi does not offer refunds for unused subscription time when you delete your account, except where required by law or issued by Lemon Squeezy. For billing details that cannot be verified automatically, or another server-side deletion request, email comixi@proton.me from your account email address if possible. Please do not send passwords or session tokens. We will check any subscription before deleting the account. Lemon Squeezy and other providers may keep records under their own policies.
Changes and contact

We may update this policy as Comixi changes. The date above will show when it was last updated. For questions, support, or privacy requests, write to comixi@proton.me.
